4-20 mA Output

for Ex-i areas

WAGO has added another 2-channel analog output module to its Ex-i portfolio for connecting actuators in areas subject to explosion. The 750-586 is approved for the highest safety level Ex [ia] and is therefore suitable for all actuators in Zones 0, 1, and 2. The 2-channel analog output module installed in Zone 2 offers a signal current of 4 to 20 mA. Similar to the 750-585 with 0 to 20 mA, the 750-586 is both ATEX and IECEx certified. Thus the use of actuators in areas subject to explosion – in mining and in atmospheres where gas and dust may accumulate, for example – is guaranteed to be safe.

The outputs of both analog output modules are designed to resist short circuits. In addition, the field and system levels are galvanically isolated from one another. In the course of the approval process for the 750-586, the safety level of the 750-585 was also re-categorized from Ex [ib] to Ex [ia].

Approved for a wide variety of applications: with its fieldbus-independent design that features finely modular components, the WAGO-I/O-SYSTEM readily meets all the requirements made of distributed fieldbus systems. Its modular basic concept is also reflected in its support for numerous fieldbus systems. Depending on the application, it is possible to choose from among fieldbus couplers and fieldbus controllers for different protocols. A total of more than 400 different modules make the WAGO-I/O-SYSTEM 750 a scalable solution that is easy to integrate and features an unbeatable price-performance ratio.
